Manufacturing Discipline And Inspection Control For Stable Project Supply

It Never Speaks, But Always Protects

This page shows the manufacturing, inspection, and qualification work behind GreenPower’s medium-voltage switchgear supply, including assembly, testing, and document support before release.

Manufacturing Overview

Our Four Manufacturing Bases

GreenPower’s medium-voltage production is organized across four manufacturing areas covering switchgear systems, vacuum circuit breakers, insulation parts, and copper components.

Switchgear manufacturing base

SwitchgearManufacturing Base

Supports medium-voltage switchgear assembly, panel integration, internal arrangement, and project-based cabinet production.

Vacuum circuit breaker manufacturing base

Vacuum Circuit BreakerManufacturing Base

Supports vacuum circuit breaker production, mechanism assembly, functional matching, and preparation for switchgear projects.

Insulation components manufacturing base

Insulation ComponentsManufacturing Base

Supports insulation parts used in medium-voltage switchgear systems, with coordinated component preparation for production and supply.

Copper components manufacturing base

Copper ComponentsManufacturing Base

Supports copper conductors, connection parts, and matched conductive components used in medium-voltage distribution equipment.

Production Process

From Technical Review To Dispatch Readiness

GreenPower’s switchgear production moves through design review, material preparation, cabinet fabrication, wiring, testing, cleaning, and dispatch preparation before shipment.

Order Review And Design

Production starts with order confirmation, technical review, and design preparation based on the approved project requirement.

Procurement And Material Preparation

Matched components, supporting parts, and required materials are prepared according to the confirmed design and supply scope.

Cabinet Fabrication And Primary Assembly

Cabinet processing and primary assembly are carried out as the switchgear structure and main internal arrangement are formed.

Busbar Work And Secondary Wiring

Busbar preparation, internal conductor work, and secondary wiring are completed according to the required configuration.

Mechanical Adjustment And Electrical Pre-Test

Mechanical adjustment and electrical pre-test are completed before high-voltage verification and final release preparation.

Withstand Test To Final Dispatch

Withstand-voltage and related checks are followed by cleaning, finishing, packing, and dispatch preparation before shipment.

Quality Assurance

Quality Assurance And Inspection Control

Inspection follows the manufacturing process from incoming verification through assembly, wiring, interlock checks, withstand and partial-discharge testing, and final outgoing release.

Incoming Verification

Key materials and matched components are checked before entering the production flow.

Structure And Assembly Inspection

Cabinet structure, assembly quality, and internal arrangement are checked during production.

Wiring And Circuit Verification

Secondary wiring, line identification, and circuit continuity are checked before final testing.

Mechanical Interlock Check

Mechanical movement and interlock functions are checked to confirm proper operating coordination.

Insulation Withstand And Partial Discharge Test

Electrical verification includes insulation-related checks together with withstand-voltage and partial-discharge testing as required.

Final Outgoing Inspection

Appearance review, final confirmation, and outgoing release checks are completed before packing and dispatch.
